The answer is 306.0000 square units.
We have two pairs of equal sides; one pair of length 3.4 cm each and one pair od 3.3 cm each.
There quadrilateral (four-sided shape) that meet this first condition is:
Parallelogram
Rhombus
Rectangle
The only shape that has at least 3 angles of 90° would be RECTANGLE as the other shapes don't have right angle
OK this is how it goes: Multiplying a number <1 with 2/3 another number <1, will give a fraction of a fraction, and part of a fraction is an even smaller fraction. Another way of looking at it: Fractions less than one have numerators smaller than their denominators. When multiplying fractions, you multiply across, so multiplying two fractions that are both less than one will always give a numerator much smaller than the denominator, and a larger denominator makes for a smaller number. I know this is very confusing but it is how you do it. It takes a while to wrap your head around it, I know.
